Which flow rate is appropriate for a standard adult nasal cannula?
Correct answer: A. 1 to 6 L/min
- A. 1 to 6 L/min
- B. 8 to 12 L/min
- C. 12 to 15 L/min
- D. 15 to 20 L/min
Explanation
A standard nasal cannula commonly delivers oxygen at 1 to 6 L/min. Higher flows can cause nasal dryness and do not provide the controlled high-concentration delivery of a reservoir mask.

About Oxygen Therapy and Airway Care
Airway care includes positioning, suctioning, coughing and deep-breathing exercises, incentive spirometry, oxygen delivery devices and humidification. Questions address indications, flow rates, safety precautions and monitoring for hypoxia or oxygen toxicity, while distinguishing nasal cannula, simple mask, non-rebreather mask and Venturi mask use.
